the second cross connecting rod comprises two handrail cross pipes hinged in the middle, the upper ends of the two handrail cross pipes are respectively connected with the upper ends of the seat side pipes on the two sides, the lower ends of the two handrail cross pipes are provided with first bent parts, and the two first bent parts are respectively connected with the lower ends of the side pipes on the two sides;

the third cross connecting rod comprises two rear cross pipes hinged in the middle, the upper ends of the two rear cross pipes are respectively connected with the two back pipes, the lower ends of the two rear cross pipes are provided with second bent parts, and the two second bent parts are respectively connected with the lower ends of the seat side pipes on the two sides.

The improved structure comprises a set of front foot parts and a set of rear foot parts, wherein the lower ends of the side tubes and the lower ends of the first bending parts are connected to the front foot parts, and the lower ends of the seat side tubes, the lower ends of the back tubes and the lower ends of the second bending parts are connected to the rear foot parts.

The improved structure is characterized in that each back tube is sleeved with a sliding piece, the sliding pieces can slide up and down along the back tubes, and the upper ends of the side tubes and the upper ends of the rear cross tubes are connected with the sliding pieces.

In a further improvement, the first bending part is bent downwards.

In a further improvement, the second bending part is bent upwards.

In a further improvement, the upper end of the handrail cross pipe extends outwards to form a handrail supporting part.

The further improvement, back crossing pipe is flat pipe, and the bearing capacity of flat pipe is better, makes the third cross connecting rod more stable.

Through the utility model provides a technical scheme has following beneficial effect:

the lower ends of the handrail cross pipe and the rear cross pipe are respectively provided with the first bending part and the second bending part, so that on one hand, the included angle of the cross pipes is changed, the supporting strength is improved, the folding chair is designed to be lower in seat height and simultaneously can keep stability, on the other hand, the upper end and the lower end of the second cross connecting rod and the upper end and the lower end of the third cross connecting rod can be synchronously folded when the base folding chair is folded, and the folding effect is remarkably improved.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a low-seat folding chair comprises a folding chair frame and a supporting cloth (not shown) installed on the folding chair frame, wherein the folding chair frame comprises a group of parallel back tubes 11, first cross connecting rods positioned on two side surfaces, second cross connecting rods positioned on a front vertical surface and third cross connecting rods positioned on a rear vertical surface, the first cross connecting rods comprise seat side tubes 21 and side tubes 22 hinged in the middle, the lower ends of the seat side tubes 21 are connected with the lower ends of the back tubes 11, and the upper ends of the side tubes 22 are connected with the back tubes 11.

The second cross connecting rod comprises two handrail cross pipes 31 hinged in the middle, the upper ends of the two handrail cross pipes 31 are respectively connected with the upper ends of the seat side pipes 21 on the two sides, the lower ends of the two handrail cross pipes 31 are provided with first bending parts 311, the first bending parts 311 are bent downwards, even if the included angle of the lower ends of the two handrail cross pipes 31 is smaller than the included angle of the upper ends of the two handrail cross pipes 31, and therefore the supporting strength of the second cross connecting rod is improved. The two first bending portions 311 are respectively connected to the lower ends of the side tubes 22 at two sides.

The third cross link comprises two rear cross tubes 41 hinged in the middle, the upper ends of the two rear cross tubes 41 are respectively connected with the two back tubes 11, the lower ends of the two rear cross tubes 41 are provided with second bent parts 411, the second bent parts 411 are bent upwards, and the two second bent parts 411 are respectively connected with the lower ends of the seat side tubes 21 at two sides.
